Past Project: Changing Arctic Transpolar Systems

With the joint Russian-German research project „CATS – The Changing Arctic Transpolar System“ (March 1, 2017 – February 29, 2020), a consortium of 10 research institutions and universities in Russia and Germany investigated how climate change will affect the highly sensitive Arctic environment and to what extent these changes may impact the climate in Europe. The main research regions are the western Laptev Sea shelf and continental slope, Vilkitsky Strait, and Cape Baranov (Severnaya Zemlya), located in the Russian EEZ. This topographically complex region features strong polynyas, sea-ice formation, and a variety of shelf processes that impact the circulation and…

Past Project: The Past Nutrient Cycle in the Labrador Sea

Linking changes in productivity and nutrient distribution in the Labrador Sea to ocean-atmosphere climate dynamics from the Glacial to today Ocean Frontier Institute (OFI), Postdoctoral Fellow (PDF) Dr. Kristin Doering Supervisors: Prof. Dr. Stephanie Kienast Prof. Dr. Martin Frank In the present and past ocean nutrient distribution and utilization in high latitudes are closely coupled to ocean-atmosphere dynamics and strongly influence the nutrient supply to the thermocline of low latitudes and the deep ocean. The Labrador Sea (LS) is a key area for such climatic and oceanographic interactions in the Northern Hemisphere as it links the Arctic Ocean and the…

Past Project: Collaborative Research Center 754 

“Climate-Biogeochemistry Interactions in the Tropical Ocean” The Collaborative Research Center (SFB 754) addresses the relatively newly recognized threat of ocean deoxygenation, its possible impact on tropical oxygen minimum zones and implications for the global climate-biogeochemistry system. The overall goal of the SFB 754 is to improve understanding of the coupling of tropical climate variability and circulation with the ocean’s oxygen and nutrient balance, to quantitatively evaluate the nature of oxygen-sensitive tipping points, as well as to assess consequences for the Ocean’s future. The key questions of the SFB 754 are: How does subsurface dissolved oxygen in the tropical ocean respond…
